Then, the process returns back to Step 13A.
  • Step 14A If, in Step 14A, the address is that or the fire detector, then, in Step 24A, transmission is fixed to transmission 1. If, in Step 14B, the address is that of another fire detector, then, in Step 24B, the transmission is fixed to transmission 2. Thereafter, in either case, in Step 16, the address is indicated by indicator section 8. In other words, three LED45 of the operation indicator section 36 of Fig. 4 which correspond with the numbers of the address are lit. Then, the process returns back to Step 13A where preparation is made for the confirmation of the next fire detector.
  • performing the operations in accordance with the above-described calling selecting method and sending out calling commands, in a plurality of transmission modes allow confirmation of the transmission mode of the terminal device responding to the command and automatic selection of the transmission mode. Therefore, even if the transmission mode of the fire detector is not known, it is possible to carry out address setting and confirmation.
  • Step 1 of Fig. 9 pressing, for example, digit key 39 and power key 37 of Fig. 4 simultaneously causes the operation mode to be set in setting mode.
  • switches 12 and 13 switch to either transmission circuit 10 side or transmission circuit 11 side, and switch 14 is closed, causing the power to be turned on.
  • the microcomputer determines whether the mode is address setting mode or confirmation mode. In this case, the mode is setting mode, so that, in Step 3A, by way of transmission 1 the transmission for address searching is started. A command is generated to cause the fire detector to send its address. The address is received by the microcomputer.
  • Step 4A the microcomputer determines whether or not the address has been sent back properly. If it has been sent back properly, then, in Step 6A, this address is indicated by indicator section 8. That is, three LEDs 45 of the operation indicator section 36 of Fig. 4 which correspond to the numbers of the address are lit. Thereafter, or if the address which has been sent back in Step 4A is not that of the fire detector , in Step 3B, by way of transmission 2 transmission for address searching is started. A command is generated to cause the fire detector to send its self-address. This address is received by the microcomputer.
  • Step 4B the microcomputer determines whether or not the address has been properly sent back. If it has been properly sent back, in Step 6B, the address is indicated by indicator section 8. That is, three LEDs 45 of the operation indicator section 36 of Fig. 4 which correspond to the numbers of the address are lit. Thereafter, or if the address which has been sent back in Step 4B is not that of the fire detector in Step 31, the microcomputer determines whether or not there has been an address indication. If there has not been an address indication, then, in Step 5, an occurrence of a transmission error is indicated by indicator section 8. That is, LED44 of the operation indicator section 36 of Fig. 4 is lit. Thereafter, the process returns back to Step 4A and the confirming device waits for the fire detector to be connected properly or for it to be replaced by a good one.
  • Step 31 If there has been an address indication in Step 31 then in Step 7 of Fig. 10, the microcomputer determines whether or not the address to be set has been input. The address is input as described above.
  • Step 7 If the setting address has not been input in Step 7 the process returns back to Step 4A and the above-described operations are repeated. If it has been input, the process proceeds to Step 8 and the microcomputer determines whether or not the setting has been executed, that is whether or not the execution key 38 of Fig. 4 has been pressed.
  • execution key 38 has not been pressed, the confirming device waits for the execution key 38 to be pressed, with the setting address indicated by the indicator section. If execution key 38 has been pressed, the address setting is completed. The LEDs 45 which have been blinking up to this time are now lit. This means that three LEDs 45 which correspond to the numbers of the address which have been input are now lit.
  • Step 9A the set address along with the address setting command, etc. are transmitted to the corresponding fire detector by way of transmission 1 to change the address which is stored in an internally provided storage means such as, for example, EEPROM.
  • Step 9B the address to be set is transmitted along with the address setting commands, etc. to the corresponding fire detector by way of transmission 2 to change the address stored in an internally provided storage means, as, for example, EEPROM.
  • Step 10A the address which has been changed and set is sent back by way of transmission 1 for confirmation.
  • Step 10 B the address which has been changed and set is sent back again by way of transmissions 2 for confirmation.
  • Step 11 the microcomputer determines whether or not the address which has been sent back matches that set at the address confirming device as described above. If they do match each other, the process returns back to Step 4A and the confirming device prepares for the setting of the next fire detector. If they do not match each other in Step 11, then, in Step 12, an occurrence of a setting error is indicated by indicator section 8. That is, LED44 of the operation indicator section 36 of Fig. 4 is lit. Thereafter, the process returns back to Step 4A and the confirming device waits for the fire detector to be connected properly or for it to be replaced by a good one.
  • Step 1 pressing, for example, power key 37 of Fig. 4 alone causes the operation mode to be set in confirmation mode.
  • switches 12 and 13 switches to either transmission circuit 10 side or transmission circuit 11 side, and switch 14 is closed, causing the power to be turned on.
  • the microcomputer determines whether the mode is address setting mode or confirmation mode. In this case, the mode is confirmation mode, so that, as described above, in Step 13A of Fig. 9, by way of transmission 1 transmission for address searching is started. A command is generated to cause the fire detector to send its address. This address is received by the microcomputer.
  • Step 14A the microcomputer determines whether or not the address has been properly sent back. If it has been properly sent back, then, in Step 16A, this address is indicated by indicator section 8. That is, three LEDs 45 of operation indicator section 36 of Fig. 4 which correspond to the numbers of the address are lit. Thereafter,or if the address which has been sent back in Step 14A is not that of the fire detector, in Step 13B, by way of transmission 2 transmission for address searching is started. A command is generated to cause the fire detector to send its address. This address is received by the microcomputer.
  • Step 14B the microcomputer determines whether or not the address has been properly sent back. If it has been properly sent back, then, in Step 16B, this address is indicated by indicator section 8. That is, three LEDs 45 ot the operation indicator section 36 of Fig. 4 which correspond to the numbers of the address are lit. Thereafter, or if the address that has been sent back in Step 14B is not that of the fire detector , in Step 32, the microcomputer determines whether or not the address has been indicated. If it has not been indicated, then, in Step 15, an occurrence of a transmission error is indicated by indicator section 8. That is, LED 44 of the operation indicator section 36 of Fig. 4 is lit. Thereafter, when the operation in Step 15 has been completed, or if the address has been indicated in Step 32,the process returns back to Step 14A and the confirming device prepares for the confirmation of the next fire detector.
  • the processing carried out in accordance with the all-signal sending method and the use of all of the transmission modes when calling commands or the like are sent out makes it unnecessary to select the transmission mode, so that incorrect selection of transmission modes will not occur.
  • switching the transmission mode with a change-over switch allows use of a fire detector serving as a terminal device having different transmission modes to be used by matching the modes, so that sending out calling commands, in a plurality of modes, allows confirmation of the transmission mode of the terminal device responding to the command and automatic selection of the transmission mode.
  • Using all the transmission mode commands when calling commands or the like are sent out makes it unnecessary to select the transmission mode, which eliminates the problem of erroneous transmission mode selection. Therefore, even when, in particular the external appearance of terminal devices is the same, it is possible to immediately perform without delay address setting and confirmation of each terminal device such as, for example, a fire detector.
  • the confirming device upon completion of address setting and confirmation of a fire detector by the use of the above-described setting mode, the confirming device is allowed to wait at the time the address is checked (Step 4, etc.), so that it can prepare for the address setting and confirmation of the next fire detector. Therefore, a user which is not experienced or skilled in handling the fire detector does not need to turn on the power of the address confirming device 30 each time the fire detector is replaced. This allows him to set and confirm the address of the fire detector efficiently and accurately.
  • the confirming device Upon completion of address setting and confirmation of a fire detector by the use of the above-described setting mode, the confirming device is allowed to wait at Step 14A, so that it can prepare for the address setting and confirmation of the next fire detector. Therefore, even if the user is not experienced or skilled in handling the fire detector or the like, he does not have to turn on the power of address confirming device 30 each time the fire detector is replaced. This allows him to confirm the address of the fire detector efficiently and accurately. In addition, in this case the unexperienced user cannot carelessly change the address which has already been set, so that it is safe from the viewpoint of fire detector control.
  • switch 14 functions as an auto-power off switch which automatically turns off under the control of microcomputer 5 after a predetermined time has elapsed.
